uniform strength, have been devised .but thelr construction was soexpenslve .as to prohibit their manufacture.

The objects of my invention are -to provide a torpedo of inexpensiveconstruction which may be made of any desired size and strength andwhich will always be of practically uniform strength throughout itsentire casing and to provide a novel method for making the body of thecasing.

These objects, and other advantageous vends which will be describedhereinafter, I attain in the following manner, reference bein had 'to'the accompanying drawing in whic Figure 1 is a perspective view of atube which is to be formed into the body of the casing with a spheroidalbottom,

Figure 2 a perspective view of the tube shown in Figure 1 having in-accordance with my novel method, and speroidal bottom formed thereon,

Figure 3 a. central' section throu h a. torpedo constructed inaccordance wit my invention and having a coating of adhesive materialapplied thereto. Y

Referrin to the drawings, 1 indicates a casing having a spheroidalzbottom 2 and an open top 3. A cap 4 ycloses top 3 and is securedto'casing 1 by adhesive material. An suitable explosive material 5 isplaced wit in the casing. If desired a reinforcing band 6 is secured tocap 4 in casing l by adhesive material. A'coating of adhesive 7 isapplied to the casing to reinforce the same.

The methods of making my improved torpedo consists of cuttingcylindrical tubes shown in Figure. 1 and forming the spheroidal bottom 2as shown in Figure 2. This spheroidal bottom may be formed Iin anysuitable manner, preferably by softening the bottom of the tube andtwisting the bottom to take a spheroidal shape. The softening of thetube, if made of paper, may be done, by dipping it in water and if ofcomposition b-y dipping i-t into a solvent and then drying. The casing 1is filled with the exploslve material 5 and cap 4, which may be made inany suitable manner, is placed over casing 1 to cover the same. Ipreferably coat the inner side walls of the cap with adhesive materialso that it will adhere to the casing. If desired the cap may be securedtothe casing solely by the reinforcing strip 6 which is glued to thecasing and to v the cap. If desired the torpedo is then dipped into abath of adhesive material to reinforce the same. The ltorpedo is thendried and is ready for use.

A torpedo made in this manner may be of any desired length withoutaffecting its uniformity in strength, because varying the length ofcasing 1 does not effect its strength.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent isz- 1. A torpedo including a tubular casinghaving its upper end o n and its lower end formed into a spheroi albottom; explosive material in `the casing, and a tubular cap having aflat top secured to and closing the upper end of the casing.

Q A torpedo including a cylindrical casing having its upper end o en andits lower end formed into a sphero1dal bottom; explosive material in thecasing, and a cylindrical cap having a flat top secured to and closn theupper end of the casing.

3. i torpedo including a tubular casing having its upper end open andits lower end formed into a spheroidal bottom; explosive material in thecasing; a tubular cap having a flat top secured to and closing the upperend of the casing, and a reinforcing band secured to the cap and thecasing.

4. A torpedo including a tubular casing having its upper end open andits lower end name to this specification in the presence formed into aspheroidal bottom; explosive of two subscribing witnesses. material inthe casing; atubular cap having a Hat top secured to and closing theupper I ACHILLO FABRIZIO' 5 end of the casing, and a coating of adhesiveVitnesses:

material on the cap and the casing. XVARREN W. B0ULDEN In testimonywhereof I have signed my Mozm B. BOULDEN.
